STARCH- TABLE.

SPECIFICATION forming part of Letters Patent No. 248,734, dated October25, 1881.

Application tiled July 27, 1881. (No model.)

To all whom it may concern:

Be it known that I, ROGER \V. GRAVES, of the city of Buffalo, in thecounty of Erie and State of New York, have invented a new and usefulImprovement in Starch-Tables,of which the following is a specilcation.

This invention rela-tes to an improvement in the tables or trays whichare employed in starch-factories for the separa-tion ofthe starch fromthe gluten and other refuse. These tables are composed of tlat guttersslightly inclined and of considerable length, frequently exceeding ahundred feet. The starch-water is discharged upon the highest end of thetables and runs over the same in a thin tilm, depositing the starch,while the gluten and other rel'use run oli. The starch is removed fromthese tables by shoveling the starch into handcars or other receptacles,by which the starch is conveyed to the washing-vats or otherreceptacles. This mode of removing` the starch is very laborious, andconsumes a great deal ot' time; and it is the object ot' my invention tofurnish a more expeditious and elt'ective means of removing the starchfrom the tables to the place where the starch is further treated orstored until treated; and my invention conv sists, to that end, of vanendless-belt conveyer arranged over or on lone side ot' thestarchtables, and moving so as to convey the starch which is shoveled onthe belt from the table tothe proper receptacle or place of deposit, aswill be hereinafter fully set forth.

In the accompanying drawings, Figure l is a longitudinal section, andFig. 2 a cross-section, of a set ot'starch-tables provided with myimprovements.

Like letters of reference refer to like parts in both of the ligures..

A represents a series ot starch-tables, three or four being usuallyarranged side by side between every two rows of posts of the build- Brepresents the endless conveyer-belt, arranged centrally andlongitudinally over the starch-tables. The belt B runs over two pulleys,C C', and over intermediate supporting-V rollers, l), arranged atsuitable distances apart. The pulleys O O and rollers D turn injournalboxes which are attached to hangers E, suspended from the timbersoverhead and braced in any suitable and well-known manner. The shaft ot'the head-pulley O is provided with a driving-pulley or gear-wheeh'F, towhich motion is imparted from any convenient source. The tail-pulley Ois supported injournal-boxes, which are made adjustable by screw-beltsg, or other suitable means, to permit the belt to be tightened whennecessary.

h is a scraper-plate, which bears against the belt B on the face ot' thehead-pulley O, and detaches from the belt all particles of starch whichmay adhere thereto. The scraper-plate It is held against the belt by aspring, t', or weights, as may be desired.

K represents the washing-vat or other receptacle into which the starchis discharged from the belt B. The latter is arranged at such a heightabove the tables that the starch deposited upon the tables under thebelt can be easily reached and removed from the tables and lifted uponthe belt. The lumps of starch are not disturbed after being placed uponthe conveyer-belt. until they are discharged into the receptacle K orother place of deposit, and 7 are therefore carried bythe belt iu anunbroken state to the place ot' deposit, thereby preventingany loss ofthcstarch while in transit,wliich occurs when the moist lumps ot starchare broken up or agitated, as the moist lumps rapidly dissolve intoaliquid under these circumstances.

I aman-'are that endless belts have been used as conveyers in variousstages of the manufacture ot'starch, and I do not broadly claim suchuse; but

l claim as my invention- The combination, with a starch-depositingtable, A, of an endless conveyer-belt, B, arranged horizontally over thetable at a height can be conveniently deposited upon the conveyer-belt,for the purpose of being conveyed to the proper receptacle,substantially ask set forth.
